Method for using java servlets as a stack based state machine

Abstract

A client module downloaded by web browser from a server receives authentication information to open a smart card in a card reader and to initiate a secure network connection to a first server module running on a server. The client module calls a second server module running on the server. And the client module receives a new application for the smart card. Then the client module causes the smart card to delete an old application and load the new application. Each of the operations performed by client module occurs in a single session.

What is claimed is: 
     
       1. A method, comprising the operations of:
 using authentication information to open a smart card in a card reader and to initiate a secure network connection to a first server module running on a server; 
 calling a second server module running on the server, wherein the second server module is a reprovision module identified in a command received from another server module running on the server; 
 receiving a new application for the smart card; and 
 causing the smart card to delete an old application and load the new application, wherein each of the operations is performed in a single session by a client module downloaded by a web browser from the server and wherein the client module executes on one or more processors. 
 
     
     
       2. The method of  claim 1 , further comprising the operation of:
 instructing the new application to generate a Public Key Infrastructure (PKI) keypair.

       4. The method of  claim 1 , wherein the authentication information includes a card unique ID (CUID) received from the smart card. 
     
     
       5. The method of  claim 1 , wherein the authentication information is obtained at least in part through the use of a pluggable authentication module (PAM). 
     
     
       6. The method of  claim 1 , wherein the secure network connection is based at least in part on a master key for the smart card stored in a hardware security module (HSM) on the server. 
     
     
       7. The method of  claim 1 , wherein the applications are applets and the server modules are servlets. 
     
     
       8. The method of  claim 1 , wherein the client module is an applet.
